Architecture description

The JTAGICE mkII architecture is shown in the block diagram in Figure 5.1, “JTAGICE mkII block diagram”

Power supply

The JTAGICE mkII power supply is implemented as shown in figure XXX. The power switch found on the back of the JTAGICE mkII turns on both the External and USB power, an internal switch will select which power source to use. The external power supply is default select if it's provides sufficient power.

Note: The JTAGICE mkII cannot be powered from target application.

Level converters

The purpose of the Level Converters is to provide successful communication with target boards running at voltages different than the JTAGICE mkII itself. The level converter is designed to support target voltages from 1.8V to 5.5V.

Probe

The Target Adapter is pictured below. The 20wire flex-cable connects the Target Adapter to the JTAGICE mkII. The Target Adapter has two 10-pin connectors that have identical pin-out, and signals. Use the one that best fits the target board. Only one of the connectors should be connected at any given time.

For further information on how to connect the probe to the target application, see section Connecting the JTAGICE mkII
